Since it’s asking for square inches on a rectangular prism, this is solving for surface area. So we use the following formula:
2(h*w)+2(h*l)+2(w*l)=A

2(10*8)+2(10*12)+2(8*12)
2(80)+2(120)+2(96)
160+240+192
592

592 sq. in.

Resuelve las siguientes ecuaciones: -x^2 - x =0 -X^2 + 12x = 0 3X^2 - 9x = 0 X^2 - 2x - 3 = 0
vaieri [72.5K]

Responder:

<em>a) 1 </em>

<em>b) 12 </em>

<em>c) 3 </em>

<em>d) -1 y 3 </em>

Explicación paso a paso:

Dadas las siguientes ecuaciones;

a) x²-x =0

x² = 0+x

x² = x

x = 1

b) -x²+12x = 0

-x² = -12x

x² = 12x

x = 12

c) 3x² - 9x = 0

Suma 9x a ambos lados

3x²-9x+9x = 0+9x

3x² = 9x

3x = 9

x = 9/3

x = 3

d) x²-2x-3 = 0

x²-3x+x-3 = 0

x(x-3)+1(x-3) = 0

(x+1)(x-3) = 0

x+1 = 0 y x-3 = 0

x = -1 y 3

I NEED HELPPP ON THIS PLZZZ
Anika [276]

Answer:

Perimeter of ABCD = <u>56 units</u>

Perimeter of WXYZ = <u>140 units</u>

Step-by-step explanation:

<u>To find the perimeter of ABCD, find the sum of all sides</u>

18 + 18 + 10 + 10 = 56

<u>To find the side lengths of WXYZ, use the equation:</u>   \frac{image}{pre-image}

45/18 = 2.5

<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>

<u>Multiply the pre-image side lengths by 2.5</u>

18 × 2.5 = 45

10 × 2.5 = 25

<em>45 and 25 of the new side length of WXYZ</em>

<em />

<u>To find the perimeter of  WXYZ, find the sum of all sides.</u>

45 + 45 + 25 + 25 = 140

WX = 45, XY = 25, YZ = 45, ZW = 25

|13x-4|+12 &lt; 56<br> Anybody know this cuz I do
Ronch [10]

Answer:

\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)

Step-by-step explanation:

<u>Inequalities with Absolute Value</u>

We must recall the following rule:

\text{If  }|M|0

Then:

-N

We have the following inequality:

|13x-4|+12 < 56

Subtracting 12:

|13x-4|< 56-12

|13x-4|< 44

Applying the rule:

-44

Adding 4:

-44+4

Operating:

-40

Dividing by 13:

\displaystyle -\frac{40}{13}

The solution expressed in interval form is:

\boxed{\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)}
